Is it possible to get "location semantics" with
I don't think it is possible, but I wanted to confirm here.
My goal is to be platform agnostic, and not get mixed separators in path
names, in order to accomplish this I don't think I can use <condition/>.
While I prefer to use "pure ant", in this case I think the <if/> is better
than lots of ${path.separtor}'s in strings.
Consider this example:
OUTPUT: (note mixed separators)
C:\temp>ant -version
Apache Ant version 1.7.0 compiled on December 13 2006
C:\temp>ant
Buildfile: build.xml
[echo] dir.works = C:\temp\false\demo\path
[echo] dir.fails = C:\temp/false/demo/path
BUILD SUCCESSFUL
Total time: 0 seconds
>From this build.xml:
<?xml version="1.0" encoding="utf-8"?>
<project name="condition-property-semantics-test">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<if>
<istrue value="${some.property}" />
<then>
<property name="dir.works"
location="${basedir}/true/option" />
</then>
<else>
<property name="dir.works"
location="${basedir}/false/demo/path" />
</else>
</if>
<!-- not equivalent to above on windows, ${dir}
will have both forward and backward slashes -->
<condition property="dir.fails"
value="${basedir}/true/option"
else="${basedir}/false/demo/path">
<istrue value="${some.property}" />
</condition>
<echo>dir.works = ${dir.works}</echo>
<echo>dir.fails = ${dir.fails}</echo>
</project>
Anyone have any other suggested solution? Thanks.

Could you spare a "temporary" property? Something like
<condition property="dir.fails.tmp"
value="${basedir}/true/option"
else="${basedir}/false/demo/path">
<istrue value="${some.property}"/>
</condition>
<property name="dir.fails" location="${dir.fails.tmp}"/>
<echo>dir.fails = ${dir.fails}</echo>

I would use several properties files and load the one needed for the current
environment.
<property file="${os.name}.properties"/>

Have you seen paths with mixed separators actually cause problems?
I'm no longer on Windows but my experience was that it didn't matter as
Windows handled paths with mixed separators correctly.
